Just when we thought Jamie Dornan had the Christian Greygig in the bag, the seemingly never-ending plot to find Fifty Shades of Grey's leading man thickens! While Jamie did reportedly have a "really good read" on Friday, it turns out he wasn't the ONLY one!

Billy Magnussen -- who has appeared in As the World Turns and nominated for a best featured actor Tony this year for Vanya and Sonia and Masha and Spike -- ALSO tested for the role, according to The Hollywood Reporter. What's more, BOTH actors tested with director Sam Taylor-Johnson and read opposite Dakota Johnson. Innnteresting.

The site goes onto report that the producers' shortlist to cast from now includes just Jamie and Billy. That said, I dunno about you, but I'm taking that to mean that the "usual suspects" we keep throwing around -- like Alexander Skarsgard, Ian Somerhalder, Matt Bomer, Alex Pettyfer, etc. -- are officially out of the running!Looks like it has come down to this, people -- Jamie vs. Billy!

Billy isn't English like the better lot of people associated with this flick, but I'd be all for that, being that Christian Grey is an American character! He also has experience replacing another actor in a big flick -- having recently replaced Jake Gyllenhaal as Rapunzel’s Prince in Disney’s upcoming big screen version of Into the Woods, and he'll also begin filming a lead role in the HBO series The Money. Definitely sounds like he's got the chops. And he's the right age at 28. And he looks the most like Charlie Hunnam than Jamie, so if a blonder Christian Grey is what E.L. James & Co. decided they want, then he's definitely their man ...

At the same time, Jamie's an up-and-coming hottie who could totally do brooding and mercurial and has impressive credentials to boot!

Either way, let's hope it all boils down to whichever actor had the best chemistry with Dakota. Because no matter how quickly the suits want to get Christian cast, the sparks between their leads is obviously a factor they cannot afford to lose.
